He's been nominated four times (three for Best Actor, one for Best Supporting Actor), but has never had the opportunity to pull his acceptance speech out of his tuxedo pocket.

After he plays the lead in the New Regency film, "The Crowded Room," DiCaprio, one of the finest actors of our time, may want to brush up on his thank you's.

According to The Hollywood Reporter, the Golden Globe-winning actor ("The Wolf Of Wall Street") is now closer than ever to playing a role he's been chasing for two decades: Billy Milligan, the first person to ever be acquitted using the multiple personality disorder defense in a court of law.

In addition to playing Milligan, DiCaprio will also serve as producer with Jennifer Davisson and Alexandra Milchan. Jason Smilovic ("Lucky Number Slevin") and Todd Katzberg have been tapped to adapt the script from Daniel Keyes' nonfiction book about Milligan's trial in Ohio in the late 1970s after he was charged with robbery and raping three women on the Ohio State University's campus.

Milligan, who died in December 2014, pled insanity and his lawyers argued that two of his 24 alternate personalities committed the crimes unbeknownst to him. Adalana, his lesbian personality, was allegedly responsible for the rapes, while Ragan, his Yugoslavian communist personality, supposedly committed the robbery.

Although the project has been collecting dust for almost a decade, it has been been coveted by Hollywood and linked to high profile directors like James Cameron.

DiCaprio, who has been interested in bringing the character to the big screen since 1997, will likely be back to full acting form following "The Revenant," his first movie after his one-year hiatus and director Alejandro G. Inarritu's first film after his Best Picture Oscar-winner, "Birdman."
